Summary
As well as being the realm of the first stars, the high-redshift regime is a window on some of the most metal-rich components in our Universe, the massive galaxies destined to become today's ellipticals and the black holes at their centres at a time of peak activity. While much has been learnt in recent years about these ‘get-rich-quick’ objects, progress is still hampered by the same limitations as apply to nearby metal-rich stars and H II regions: our methods for exploring the super solar-metallicity regime require considerable improvement before they can be considered to be reliable. I illustrate this conclusion with a few recent case studies of active galactic nuclei, star-forming galaxies and damped Lyman-alpha systems.
